World War I, when it began in 1914, was called the war to end all wars, the Great War. It was, at that time, the bloodiest conflict in history, involving more than thirty nations and costing more than seventeen million lives. It was a war fought in the trenches with machine guns and chemical weapons. For the first time in a conflict, war planes took to the skies and armed submarines lurked in the seas. The stories and emotional impact of the war are documented in 27 prints by British and American artists from the Frank Raysor Collection, on loan from the Virginia Museum of Fine Arts. The full exhibit is available September 1 to November 5.
